Dell Desktop Home Screen

Depending on your usage time, your monitor’s screen brightness can cause eye problems. For example, if you’re a professional developer, content writer, or gamer, it’ll be challenging to focus on the screen if the brightness is low or high. You’ll experience extreme eye fatigue and restlessness in the eye muscles in no time.

If you have a Dell monitor at your place, this guide will solve that problem in a breeze! 

Quick Answer

You can adjust the brightness and contrasts on Dell monitors. You can lower or increase the illumination from the Brightness/Contrast button on the monitor (some monitors will have the half white and half black sun symbol on the button).

You can also set the brightness level from the main menu of the monitor. If you have connected the monitor to the CPU, you can increase or decrease the brightness from the Windows menu

Low brightness and poor contrast of the monitor will let your eyes struggle to focus on the screen, and it can reduce productivity and cause many eye problems. Dell allows users to adjust the brightness and contrast level for comfort and convenience like most other brands. What if the brightness level is set to a higher limit, and the screen is still blurred? We have got you a solution for this as well. 

This article will serve as a guide to adjusting the brightness of Dell monitors in simple ways. Keep on reading to know more!
